CALGARY, Alberta Feb 26 (Reuters) - Canadian cash crude
prices weakened on Wednesday after Enbridge Inc
announced further apportionment on one of its main export
pipelines and a leak at the company's Griffith, Indiana, crude
terminal forced a temporary pipeline shutdown.

Western Canada Select heavy blend for March delivery settled
at $24.00 per barrel below the West Texas Intermediate
benchmark, according to Shorcan Energy brokers.

That compares with a settlement price on Tuesday of $22.50
per barrel below WTI.

Light synthetic crude from the oil sands for March delivery
also weakened to $3.25 per barrel below the benchmark, compared
with a settlement price on Tuesday of $1.25 per barrel below
WTI.

Two trading sources said Enbridge had rationed space on the
231,000 barrel-per-day Line 6B by a further 35 percent in March.

That is in addition to 10 percent March apportionment
announced last week for Line 6B, which carries crude between
Griffith, Indiana, and Sarnia, Ontario.

Pipeline apportionment can weigh on prices as it fans
concerns that oil sands crude will get bottlenecked in Alberta.
